CVE-2009-1891 [HIGH] Apache regression
Title: Apache regression
Summary: Apache regression
USN-802-1 fixed vulnerabilities in Apache. The upstream fix for
CVE-2009-1891 introduced a regression that would cause Apache children to
occasionally segfault when mod_deflate is used. This update fixes the
problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that mod_proxy_http did not properly handle a large
amount of streamed data when used as a reverse proxy. A remote attacker
could exploit this and cause a denial of service via memory resource
consumption. This issue affected Ubuntu 8.04 LTS, 8.10 and 9.04.
